My first time trying sauna + ice bath with @sal_hotpot666, @juliezize, and @MrRyanChi. I was in pain the whole time 🥵🥶, but felt great afterwards, and it's very beneficial for health. The core mechanism is the "vascular pump effect," where rapid switching between heat and cold causes blood vessels to repeatedly dilate and contract, like giving your blood vessels a workout, thus significantly improving blood circulation, accelerating the elimination of metabolic waste, and reducing inflammation. A Finnish study tracking over 20,000 people for 20 years showed that sauna sessions 4-7 times a week (combined with cold exposure) reduced the risk of cardiovascular disease by 63% and all-cause mortality by 50%.
